I'm curious too - I checked and I don't have ready access to the reference
Paul cites and I haven't followed up 'special ordering' it from our library.

One concern I had in thinking back over the experiment was the delay between
the emission of the cascade photons.  [I assume Aspect used cascade
photons.]
